Paper Abstract

The investigation of crystallization kinetics of oxyfluoride glass 37SiO2 - 10Al2O3 - 43PbF2 - 4,5ZnF2 - 0,2LaF3 - 5,3ZnO - 0,5Nd2O3 using differential scanning calorimeter were presented. Thermal analysis were performed by using Friedman and Ozawa - Flynn - Wall methods. Reaction rate and activation energy of the crystallization process as function of reaction progress were calculated on the base of DSC measurements performed with heating rates 5, 10, 15oC/min. Glass ceramic oxyfluoride matrix were formed by thermal treatment of as melted glasses. Obtained glass-ceramic structure showed higher level of emission and less FWHM of luminescence band compared to as melted glass.
